example 1

[0029]It is well known that in vacuum insulations the insulating effect will depend upon the extent of the vacuum, as well as the configuration of the remainder of the structure, including the amount of continuous structural contact between the opposing surfaces. Such structural contact will result in heat conduction between the surfaces. The proposed insulation is analyzed to investigate the effect of such parameters on thermal characteristics. Also the state of stress in the structure under the atmospheric and inside pressure loading is studied.

—Structural Analysis

[0030]In the proposed insulation, bulges are main parts of the load-carrying structure. The bulges' area to total area determines the required inside pressure of structure to inflate the insulation. This ratio is the main parameter affecting the thermal efficiency of insulation. In other words the greater inside pressure of structure leads to a smaller required bulge area, which yields to a greater vacuum area and theref...

Abstract

A vacuum thermal insulation comprises an inflatable load-carrying structure and gas impermeable envelope with proper gates for inserting pressurized air into the structure and an evacuating vacuum chamber wherein, pressurized air is used for inflating and stiffening the load-carrying structure in order to prevent scrunching the envelope due to the atmospheric pressure. Thereby, producing vacuum in locations which are out of structure.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to vacuum thermal insulation and methods for manufacturing the same.BACKGROUND OF THE INVENTION[0002]The increasing attention to the environmental issues has led to new regulations to limit energy consumption. These measures as well as the rise continuation of the cost of energy are having significant impact on energy consumers, which have been pushed either to optimize existing technologies or adopt new technical solutions to reduce energy consumption. Modification of insulation methods to reduce heat loss or heat entry is one of these solutions.[0003]It is well known that a vacuum acts as a barrier to heat flow, and hence, certain insulating materials have included a vacuum or partial vacuum to increase their heat insulating effect. Application of vacuum insulations, which have insulation efficiency up to 7 times better than conventional insulating materials, offer the potentials for significant improvement in the...
